Ok I did an uninstall and re-install and still got the same message. Then I did it again but cleaned out the registry and deleted all the files to do with lightroom and re-installed still no luck. I still get the same error message about the cache being not readable and lightroom closes. Please help
Ok so I had to start a new catalog to get it to launch. If there is some way to repair the old catalog I would love to hear it. The fact that adobe does not have 24/7 support even for chat is a crime.
